the issue as i see it is not whether level 3 makes more (on a winning trade) than level 2 does....frankly i don't think it will.
the issue is, relative. win size relative to losing size.
if level 2 produces wins and losses that are more equal in nature (and from my testing, this happens frequently)...
then the real test for level 3 is IF it can sustain RELATIVELY large wins to losses.
i think it will do this, if you read through jack's writings, you will see that he says level 3 and 4 produce similar results (at least that's how i read his writing).
but he also writes for level 4 that you'll be gaining LESS of the trend...but you'll be scratching out more frequently.
hell i'll take 5 scratches or near scratches and a 30 tick winner.
